Topic: MyriadRF board mechanical fit

http://bunniefoo.com/novena/myriadrf-fit.png

Final board layout that I got from MyriadRF fits like a glove in Novena. I was worried we had to open a hole in the front bezel to accommodate the board but it seems they laid it out so it all fits well.

Still, I think I'll add a removeable panel to the front bezel just in case someone makes a board that has to hang off the edge.

Also, this image shows the denser Peek Array for the final version of the case. 15mm pitch staggered M2.5 bosses ftw.

bunnie,

I didn't get to pre-order during the campaign, so I won't be getting the MyriadRF board.

If I purchase the desktop now & get the stock MyriaRF board, will it fit just the same?

Regards,

Re: MyriadRF board mechanical fit

I don't think it will. The standard MyriadRF board design had to be altered in order for it to be compatible with Novena. ("through pure coincidence both projects chose the same physical connector format, so they had to move a few traces and add a few components to make their reference design fully inter-operable with our Novena design." - http://www.bunniestudios.com/blog/?p=3727)

Re: MyriadRF board mechanical fit

bunnie,

What about the routing of the coax for external antennas? Maybe I'm just not visualizing this correctly, but it looks like the SMA connector for the MyriadRF are going to be right about where the WiFi card connector is located.

Thanks

Re: MyriadRF board mechanical fit

@jaekwon The original Myriad-RF 1 module will not work with Novena, despite the fact that it will physically plug into the main board — the pin routing is different. Also, on the Novena Myriad-RF module we added an on-board oscillator and changed the RF connectors. However, the plan is to put these new Novena RF modules into general availability, so you should be able to buy one!

@kennyr We swapped the SMA connectors for U.FL on the Novena Myriad-RF module, with the idea being that these would be micro-coax cabled to bulkhead mount SMAs or similar on the port farm panel (or alternatively, if a front removable panel is made, to this — which could be neat if you use your Novena + Myriad-RF as a test/bench tool).

Those interested can clone the design files (KiCAD) and PDF exports on GitHub.

Andrew,

That makes sense, the coax jumper is easy to source. I found this in a couple minutes of searching.

For those who missed it, a photo from the Novena Twitter feed of the module fitted in place big_smile

Re: MyriadRF board mechanical fit

A short update: the first batch of Novena-RF boards have been put through their paces, correct operation confirmed and now production has been ramped up.

Below you can see a Novena mainboard + RF module being used together with the lms-suite software (for the sources see the post on the Software forum — I can only include one link/image per post).

Novena and Myriad module testing

The lms-suite application allows you to configure the transceiver, perform calibration and view an FFT display.
